The most convincing piece of evidence set forth to support the concept of sea floor spreading is the oceanic pattern of alternating reversals of Earth's magnetic field, option D.
As magma rises from the mantle and solidifies into rock at the mid-ocean ridge, it records the Earth's magnetic field at that time. Over time, the polarity of the Earth's magnetic field flips, resulting in a pattern of stripes on the ocean floor of rocks with normal and reversed polarity. This pattern has been observed on both sides of the mid-ocean ridge and is consistent with the idea that the ocean floor is spreading apart from the mid-ocean ridge. The correlation of rocks found in adjacent positions on matching continents (option A) and the fact that the mid-ocean ridge is entirely volcanic in origin (option B) are also consistent with the idea of sea floor spreading, but they are not as direct and compelling as the magnetic striping pattern. The fact that the mid-ocean ridge rises more than 2.5 kilometers above the surrounding deep-ocean floor (option C) is not directly related to sea floor spreading.

Foliation is a texture in metamorphic rocks that gives them a layered or banded appearance due to the alignment of minerals or the presence of alternating layers of different minerals.
1)Three rocks that are foliated from slide 1 are:
Slate
Schist
Gneiss
2)Non-foliated means that the rock does not have a layered or banded appearance.
The non-foliated rock from slide 1 is Marble.
The two extreme factors that create metamorphic rocks are heat and pressure.
Under extreme heat and pressure, shale can become slate or phyllite.
3)The metamorphic rock that came from an igneous rock is Schist, which can form from the metamorphism of mafic or intermediate igneous rocks.
The metamorphic rock that could have originally been sea shells is Limestone, which can form from the metamorphism of calcium carbonate-rich sedimentary rocks.
4) The metamorphic rock that could be found deep under the desert floor is Gneiss, which can form from the metamorphism of various rock types under high heat and pressure.
5)Metamorphic rocks can be found both deep under the Earth's surface and on top of the Earth's surface. However, they are more commonly found deep under the Earth's surface because metamorphism occurs at high pressure and temperature conditions that are typically found at greater depths in the Earth's crust.
6) Matching the original stone with the metamorphic rock it becomes after extreme heat and pressure:
Sandstone -> Quartzite
Shale -> Slate or Phyllite
Limestone -> Marble

The geometry of an ellipse is described by two numbers. The first is the semi-major axis, which is half the longest diameter of the ellipse, and the second is the eccentricity, which tells us the shape of the ellipse. (E)
In the field of geometry, an ellipse is a kind of shape that only exists in two dimensions and is characterized by being defined along its axes. When a plane cuts through the top of a cone at an acute angle with regard to the cone's base, the resulting shape is called an ellipse. It focuses on two different things at once. It is always the case that the total of the two distances traveled to the focal point does not change at any of the sites along the curve. Because the foci are converging at the same location, which is the center of the circle, a circle can also be thought of as an ellipse.

The highest temperature at which magnetic material can retain permanent magnetization is called the Curie temperature.
The Curie temperature (TC), also known as the Curie point, is the temperature above which certain materials lose their permanent magnetic properties, which can (in most cases) be replaced by induced magnetism. The Curie temperature was named after Pierre Curie, who demonstrated that magnetism could be lost at a critical temperature.
The magnetic moment, a dipole moment within an atom that originates from the angular momentum and spin of electrons, determines the force of magnetism. Different materials have different intrinsic magnetic moment structures that change with temperature; the Curie temperature is the critical point at which a material's intrinsic magnetic moments change direction.

The statement "The North Anatolian fault in Turkey is a 1,400 km-long fault zone made of numerous subparallel faults that split and combine, bend and straighten, and there is reason to expect major earthquakes to occur progressively farther to the west, ever closer to Istanbul" is TRUE because the fault is one of the most active and dangerous seismic zones in the world, and has generated some of the largest and most destructive earthquakes in Turkey's history.
There is reason to expect major earthquakes to occur progressively farther to the west along the fault zone, which brings them ever closer to Istanbul.
The last major earthquake on the North Anatolian Fault occurred in 1999 near the city of Izmit, killing over 17,000 people and causing widespread damage. Since then, scientists have been closely monitoring the fault for signs of increased activity and potential earthquake hazards, and have identified several segments of the fault that are currently locked and building up stress.

true/false. judge the following sentence according to the criteria given below: seismologists prefer the well-known richter scale over the moment magnitude scale because the richter scale is better for larger-magnitude earthquakes.
The claim and the arguments are untrue on both counts.
The concept of earthquake size as determined by the Richter Scale is generally recognised but poorly understood. Charles Richter first proposed the idea of a logarithmic earthquake magnitude scale in the 1930s as a means of estimating the size of earthquakes that occurred in southern California using relatively high-frequency data from local seismograph sites. The L stands for local, and this magnitude scale is known as ML. This was the initial definition of the Richter magnitude.
It became clear as more seismograph stations were built throughout the globe that the Richter approach was strictly valid only for specific frequency and distance ranges. New magnitude scales that are an extension of Richter's original concept have been created in order to benefit from the expanding number of seismograph stations that are dispersed throughout the world. These consist of surface wave magnitude and body wave magnitude (Mb) (Ms). Each is appropriate for a certain seismic signal type and frequency range. Each is comparable to the Richter magnitude within its spectrum of applicability.
